Imagine this in another time-
ELV
Dubbo, ELV IFR C402 for Narromine time 10, NPA rwy29, request traffic
DUBBO FSU
ELV standby one FSO flicks his ADS-B screen to Narromine area waits five seconds for the screen to refresh.
DUBBO FSU
ELV, I show two aircraft doing circuits rwy 36 and an IFR from Broken Hill arriving time 12, currently at 65nm and passing FL180 on descent. No other traffic.
ELV
ELV copies traffic and many thanks
DUBBO FSU
ELV and flicks screen back to area and continues to make his cuppa
Better than a CAGRO, better than UNICOM, it would have been the best system in the world. And for bugger all extra cost. Dick, if you wanted to change the world you should have started by making FSOs more versatile by giving them the gear and the coverage to look after OCTA properly. ATC looking after all CONTROLLED AIRSPACE where all the big guys fly and FS looking after everything else. ADS-B the common system looking out for everyone.
OH, I like to dream a lot
